SPECIFICATION forming part of Letters Patient No. 764,792, dated Julyl12, 1904.

Appiication aies. August 23,1902.

Serial No. 120.763. (No model.)

other end is secured to the base-board, as shown f Be it known that l,JOHN L. BOLAS, a citivgenot the United States, residing at SouthConnellsville, in `the ycounty of Fayette and State ci' Pennsylvania,have invented anew and useful Improvement in Automatic Electric Lightsfor Telephone-Booths. of which improvement the following is aspecification.

This invention relates to certain new and useful improvements iiiautomatic electric lights for telephone-booths, and has for its object adevice of this character which shall embrace novel means whereby wlienlthe oper'- ator actuatesthe bell the vibrations of the knocker willactuate the mechanism for completing a circuit, and thereby light theelectric. light within the booth.'

My invention has for its further object a ism may be returned to itsnormal position and the circuit cut out, thereby causing the light to beput out.

Vv'ith the above and other objects in view the invention consists in thenovel construction, combination, and arrangement of parts to 'oehereinafter more fully described, and

In describing the invent-ion in detail reference is liadto theaccompanying drawings, forming a part of this specihcation, andwhereparts tb roughoiit the several views, in which---v Figure 1 is atop plan view oi' the invention, showing the same in its operativeposition. Fig. 2 is a side elevation thereof looking in the direction ofthe arrow 2. Fig. 3 is a side elevation looking in the direction o arrow3.

The base-beard l is 1ot unlike those usuallyl employed in connectionwith telephones, preferably being of a rectangular form, as shown.Centrali)7 this base-board carries a bracket 2, secured by means of thescrews 3 to the board, this bracket having an upwardly-'extending member4, receiving the one end of the arm 5, secured, as at 6, by means ofscrews` this arm at it lower end-carrying a lug 7. Pivotally securedbetween this lug and the base-board 1 is a lever 8, pivoted, as at 9,and carryinga hook member 10. A'spring 11 is secured to the-.g lower endof the lever, as at 12, and at its:A

at 1 3. Slightly below its hooked end this levor carries a clamp 14,receiving the one end of the connecting member l5 in .the forni ofa Z,the upper end of this connecting inem-l ber being secured to the arm 17,carrying the -knoclter 18 at its upper end. -This arm, as

willbe understood. operates, or rather sounds. the bells common to alltelephones, as is well known in thc art. Pivoted to the base-board,

as at. 19, is an arm 20, having its one end'21'-l protruding beyond thebase-board in order that .the same may be conveniently operated. At nits rear this arm is enlarged and merges into a hook portion 21, whichis adapted for engagement with the hooked end of the lever.

This arm .is secured in its normal position by I means of thecontact-finger 22, carrying a portion of the arm `20 and pressesthereagainst.

This contact-finger is pivoted, as at 24, to the base-board and hasconnected thereto the spiral spring 25, secured, as at 26, to thecontactlinger, and, as at 27, to the base-board. A contact 28,comprising a metal piece having its portion bent at'right angles,as at29, is se cured to the base by means of the screw 30 and is adapted forengagement with the con- .tact-finger for the purpose of completing thecircuit, now to be described.

Battery 3l has a wire 32' connected thereto,- which is connected to 24,and wire 33' of this v:battery is connected to post 34, the latter beingconnected to wire 32 of vthelamp, the other wire, 33, of the lamp beingconnected to 'con-- tact-post 28.

In operation it will be noted that when the` I 'knocker is actuated thehooked end of the lever will be thrown from out of engagement with thehook member of the arm, and byreason of the tension exerted thereoncaused by the exertions of the spring 25 this arm will have its outerend thrown downwardly, 'thereby permitting the contact-finger to engagewith the contact, completing the circuit. B i reason of the and throwingthe light in. taper imparted to the upper face of thehooked end of thelever the samemay -be readily.

brought into its normal position by. Simply a ,4, .,.Hisvmwiur i hun..im i l l .from the drawings.

raising the arm .20 upwardly. as will be noted lVhile in theaccompanyingdrawingslhave illustrated the most practical embodiment ofthe invention, still it will be obvious that slight various changes oralterations may be made in the general details ot construction andcombination of parts without departing from the spirit and scope of theinvention.

Having' thus fully described the invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a device of the character described, a Source of current-su pplyhaving a lamp in circuit therewith, a bell mechanism having anoscillatory knocher connected thereto, a hooked lever carrying saidknocker, and pivotaily secured t0 thebase of said device, an arm adaptedto normallyv engage said lever, a contact-linger held normally out ofcontact by the end of said a-rm, means to establish Contact between saidiinger and a contact-piece on the oscillation of said knocker, therebyconnecting said lamp in circuit, substantially as described.

2. 1n a device of the character described, the combination of a sourceof current-supply, a bell mechanism, a circuit connecti' g a lamp tosaid supply and adapted to be closed bythe oscillation of the knocker ofsaid bell mechanism, a hooked lever pivtally mounted on the base ot'said device, carrying said knocker at one end, a. spring secured t0 theother end of said lever, a pivotedarm having a recess in one endadapte-o to be engaged by the hooked end of said lever, a springcontact-{inger normally holding open said circuit of the lamp, said armadapted to release the contact-piece upon the oscillation of the knockercarried by said hookedv lever, thereby establishing the lamp-circuit,substantially as described.

3. In a device of the character described for telephones, a source ofcurrent-supply, a bell mechanism, a lamp connected by a circuit to thesaid current-supply, a pivoted arm extending from the base of saiddevice, an inner enlarged end thereon having a recess therein adapted tobe engaged by a hooked lever, said lever carrying ther knooker of saidbell mechanism, a bracket on basholding said lever in pivotalconnection, a spring attached to' said lever to hold the samein contactwith said arm, a spring-pressed contact-finger for closing thelamp-circuit, said pivoted arm normally holding the finger out ofcontact, and

. adapted to free the same on the oscillation of the knocker of thebell, substantially as described.

In testimony whereof 1 have hereunto signed my name in the presence oftwo subscribing witnesses.
